The checkbox in the opencart filter disappears. How to fix?

Question

opencart

I click on the checkbox - a checkmark appears, then I click on the filter button - the page refreshes and shows the filtered list of products, but the checkbox from the checkbox disappears visually (if you click on the same checkbox again, the checkbox that is not visible will be removed. How is this solve, tell me please)

This looks like an obvious bug. It should be reported to the author of the module. Maybe he'll fix it.
